Proteomics Peptides & KitsPeptide sets and pools, as well as assay standardization kits are available with stable isotope labeled or unlabeled proteotypic peptides for mass-spectrometry based proteomics such as MRM assays.

Chelate Peptides (DOTA)DOTA is linked to molecules that have affinity for various structures (e.g. somatostatin receptors in neuroendocrine tumors). The resulting compounds can be bound to radionuclided and are used with a number of radioisotopes in cancer therapy and diagnosis

Immunology Standards & ControlsStandards and controls for reproducible T-cell assays such as ELISPOT and multimer assays. We offer a large variety of positive and negative control peptide pools for antigen specific T cell stimulation as well as kit to produce TCR-engineered reference samples for performance control.

Antigen PeptidesAntigen peptides represent specific epitopes for stimulation of T cells in T cell assays such as ELISPOT. We offer the corresponding MHC multimer for each antigen peptide. Antigens from different pathogens are available as well as tumor associated antigens.

Cosmetic PeptidesCosmetic Peptides such as Lysine and Cysteine Peptide are used for DPRA (Direct Peptide Reactivity Assay) for Skin Sensitization Testing. The DPRA measures the reaction of a chemical with synthetic peptides containing Cysteine (Ac‑RFAACAA‑COOH) or Lysine (Ac‑RFAAKAA‑COOH) to assess its sensitization potency. For research use only!

Alzheimer´s disease is the most prominent type of dementia and currently no causative treatment is available. According to recent studies, oligomeric species of the amyloid beta (Aβ) peptide appear to be the most toxic Aβ assemblies. Aβ monomers, however, may be not toxic per se and may even have a neuroprotective role. Here we describe a competitive mirror image phage display procedure that allowed us to identify preferentially Aβ1-42 monomer binding and thereby stabilizing peptides, which destabilize and thereby eliminate toxic oligomer species. One of the peptides, called Mosd1 (monomer specific d-peptide 1), was characterized in more detail. Mosd1 abolished oligomers from a mixture of Aβ1-42 species, reduced Aβ1-42 toxicity in cell culture, and restored the physiological phenotype in neuronal cells stably transfected with the gene coding for human amyloid precursor protein.
